Abstract
In a liquid crystal display device of a direct view type, a lenticular lens sheet is provided in the backside of a liquid crystal display panel. Light emitted to a lens of the lenticular lens sheet is first converged in the liquid crystal display panel, and then diffused. When the light is emitted from the liquid crystal display panel, the radiation distribution thereof is widened. Thus, a bright display screen even when seen from a wide angle can be realized.
